9 Claims.

The main objects of this invention are to pro- 7 vvide an improved method and form of construction of a trouser fly; to provide an improved ,method and form of trouser-fly construction which is sturdier and superior in appearance; to provide an improved method of trouser-fly construction which is so simple in its-steps of fabrication that it can be employed in the mass production of trousers and by workmen less skilled than those required for custom tailoring; and to provide an improved method and form of trouserfiy construction especially adapted for use with a slide-fastener of the present day type.

In the accompanying drawings:

Figure 1 is a plan view showing completed the first major step in this improved method and form of trouser-fly construction wherein a piece of trouser fabric, which is to constitute the inner section of the outer trouser fly, has had stitched thereto one of two temporarily interlocked fastener tapes;

Fig. 2 is a fragmentary view of the upper end of the same showing the second step, that of stitching to the trouser-fly piece of fabric the block of fabric which is to be tucked into and overlie .a part of the trouser-fly hook fastener;

Fig. 3 is a similar View illustrating the third step of the process, namely the hook stitched to the trouser-fly piece of fabric;

Fig. 4 is a similar View illustrating the fourth step, namely that of slipping the protective block of fabric into the trouser-fly hook;

Fig. 5 illustrates the next step which involves stitching the inner fly section to the piece of cloth which eventually becomes the outer section of the trouser fly;

Fig. 6 is a transverse sectional view, line 66 of Fig. 5;

taken on Fig. '7 which is a View similar to Fig. 5 shows the finished product resulting from turning inside out the two superimposed, stitched pieces of fabric which constitute the completed fly so as to conceal the edges of the fabric outwardly of *theseam; and r Fig.8 is a transverse sectional view, taken on line 88 of Fig. 7.

The present trouser fly comprises a piece of fabric I serving as the inner section of an outer trouser fly and whereon is stitched a slide fastener tape II, the hook component I 2 of a hook and eye fastener, and a hook-protecting block of fabric l3. The piece of fabric II] with the attached parts is subsequently stitched in superimposed position on the piece of trouser fabric I4 which forms the outer section of the trouser the end Ina of the piece of fabric I0 on the outerv lateral edge I0?) is formed a small V-shaped notch I which serves to guide the workman in positioning the slide fastener tape I I and stitching the block of hook-protecting fabric I3.

The fastener tape II and its complementary tape I6 are interlocked and laid on the fabric piece ID as indicated in Fig. 1, with the upper ends of the fastener tapes extending slightly beyond the guide notch I5. Thereupon the fastener tape II is stitched along the lines 9 longitudinally of the fabric piece I0, as indicated in Fig. 1. At the same time a small pieceof lining Il may be stitched to the under side of the piece of fabric ID. This first step is completed by releasing and removing the fastener tape I6 which is to be subsequently attached to the inner trouser fly.

The hook-protecting block of trouser fabric [3 is attached by a line of stitching I8 transversely of the length of said piece of fabric I0, preferably in alignment with the'notch I5, after a portion I9 of the fabric block I3 is turned inwardly upon itself, as clearly indicated in Figs. 2-4. I

The hook I2 may constitute one component of a hook and eye fastener the eye portion of which (not shown) is attached to the inner trouser fly. Thehook I2 has it base formed with an aperture 2| providing a cross bar over which may be laid a line of stitching 22 by which to attach the hook to the fly fabric I0.

Subsequent to securement of the hook I2, the

block of fabric I3 is folded outwardly over onto the piece of fabric In and tucked under an outer tached to the fabric II) are thereby completely concealed. Thereuponthe piece of fabric I0,

with these parts attached, is superimposed upon a piece of fabric I4 which is to form the outer or front section of the trouser fly, and the two pieces are stitched along the end I01; and the outer lateral side edge lb of the fabric piece II], as indicated at 24 in Fig. 5. Also the-protecting block I3 is stitched to the piece of fabric III as indicated at 25, on opposite sides of the hook l2. This preferably would be done before the piece I0 is attached to the piece I4.

In its final finished form, the superimposed stitched fabric pieces I!) and [4, as shown in Fig. 5, are turned inside out so as to conceal the edges beyond the seam 24 between the two fly sections; the hook i2 is thereby brought to exposed position Fig, 7 to permit it, in due course, to engage its eye component attached to the other trouser fly.

Modifications and variations of the construc-' tion herein shown and described may be resorted to without departing from the spirit and coverage of the appended claims.
